Engineering Contradiction Analysis
1Reliability
If transport block transmissions use different spatial parameters for different repetitions, then reliability is improved, but device complexity increases
Solution Approach 1:
The transport block transmission is segmented into multiple repetitions, where each repetition can be transmitted using different spatial parameters (such as different antenna ports, spatial relations, or transmission configuration indicator states). This allows the system to diversify the transmission paths and improve reliability by not relying on a single spatial configuration, while the segmentation enables independent optimization of each repetition's spatial parameters.
Solution Approach 2:
The patent implements dynamic selection of spatial parameters for different transport block repetitions. Instead of using fixed spatial parameters for all repetitions, the system dynamically adjusts spatial parameters (antenna ports, spatial relations, TCI states) based on channel conditions, traffic requirements, and network configuration. This dynamic approach improves transmission reliability by adapting to changing conditions while the patent manages the resulting complexity through structured parameter selection rules.
2Adaptability or versatility
If transport block transmissions use different spatial parameters for different repetitions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent systematically changes spatial parameters across different transport block repetitions. Specifically, it varies parameters such as antenna ports, spatial relations, and transmission configuration indicator (TCI) states between repetitions. This parameter variation enhances adaptability by allowing the system to respond to different channel conditions and service requirements. The patent manages the complexity of parameter determination through defined selection mechanisms that balance adaptability with implementation feasibility.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine a first set of parameters associated with a first transport block (TB) repetition of a TB and a second set of parameters associated with a second TB repetition of the TB; and determine a TB size of the TB based at least in part on the first set of parameters, the second set of parameters, or both the first set of parameters and the second set of parameters. Numerous other aspects are provided.
